3. A bolster consisting of aplate member, angles connected thereto, arolled member provided with projecting flanges located some distanceinwardly from the side edges thereof, and means for connecting saidflanges to the vertical legs of the angles fastened to the plate member;substantially as described.

4. A bolster consisting of a tcp plate, angles connected to theunderneath face o'll said plate with their horizontal legs projecting inopposite directions, a rolled member' having upwardly extending flangeslocated some distance inwardly from the side edges of said member andembracing the vertical legs of the angles .that are secured to the topplate, and fastening devices passing through said flanges and angles;substantially as described.

5. A bolster consisting of a top plate, side walls located some distanceinwardly from the side edges of said top plate, a rolled member ofapproximately the same width as the top plate and provided with flangeswhich are connected to the side walls of the bolster, and a centerbearing connected to said rolled member by fastening devices which passthroughthe same outside of the flanges thereon; substantially asdescribed.

6. A bolster consisting of a top plate, side walls, a bottomplateconsisting of a rolled member provided with upwardly projectingflanges which contact with the top plate at the end portions of thebolster, and means for connecting said rolled member and top platetogether; substantially as described.

7. A bolster consisting of a top plate, a bottom plate consisting of arolled member provided with upwardly projecting flanges, said rolledmember being spaced away from the top plate at the center of the bolsterand bent upwardly to engage the top plate at the end portions of thebolster, and lillers interposed between said top plate and rolled memberat the end portions of the bolster; substantially as described.

8. A bolster consisting of a top plate, angles connected to said topplate to form the side walls of the bolster, a rolled member providedwith upw ardly projecting flanges which are secured to the vertical legsof said angles, said member being bent upwardly so that its Vflangeswill contact with the top plate at the end portions of the bolster,fillers arranged between said top plate and rolled member cn each sideof the flanges on said member, and fastening devices extending throughthe top plate, fillers and rolled member to connect said parts together;substantially as described.

9. A car bolster in which one of the members is a special rolled beamhaving flanges arranged perpendicular to the web portion and locatedsome distance inwardly from the side edges of said web portion;substantially as described.
